Two wrecks slowed traffic Monday evening on Interstate 27 south of Amarillo, state troopers said.

Both accidents occurred in the southbound lanes near the McCormick Road overpass. Minor injuries were reported, troopers said.

The first accident happened about 7 p.m. on the overpass while maintenance crews were installing reflectors on the lane markers, troopers said. A pickup driver took his eyes off of the road and didn’t have time to react to the slower traffic near the work location and struck a pickup.

The second accident happened minutes later when the driver of a black Toyota Corolla failed to slow down for traffic and hit a pickup, the trooper said.

Traffic was diverted to the frontage road at the McCormick exit while troopers investigated the accidents.
